One of the biggest WWE stars,known as Ultimate Warrior, has passed away.

Ultimate Warrior legally changed his name from James Hellwig to his wrestler name in 1993, and was yesterday inducted into the World Wrestling Entertainment hall of fame.

Later that day, the 54-year-old collapsed outside of his hotel room in Arizona.

His cause of death has not yet been revealed.

The WWE said in a statement: "WWE is shocked and deeply saddened to learn of the passing of one of the most iconic WWE superstars ever, the Ultimate Warrior."

Ultimate Warrior began his career in the 1980s and became one of the biggest stars of WWE when he beat Hulk Hogan in the "Ultimate Challenge", winning both Hogan's WWF Championship and Warrior's Intercontinental Championship.
